> What I'd really wish for is an EU browser that 'just works'.

Have you tried Zen Browser? It's entirely open source but the core team and sponsor are European, and it's actively positioning itself as the European alternative. I've been giving it a go lately. So far, so good, and I like most of their UI/UX choices.

Not OP, but your comment had me looking into it: the fact that it's Firefox-based is reason enough to give it some consideration: the Chrome monopoly we are currently under is not compatible with a healthy and neutral web.
